Abstract
The utility model relates to an overload protection system for wire ropes of a sinking winch. The overload protection system is characterized in that: the ends of the wire ropes are connected in series with pull force sensors, or pressure sensors are mounted under bearing pedestals of hoisting pulleys; a control circuit real-timely receives detection signals coming from the pull force sensors or the pressure sensors, the first threshold of the working value of the control circuit is set as alarm control, and the second threshold is set as power-off braking control. On the basis of the electrically controlled protection function of the prior sinking winch, the overload protection system is added with overcurrent, quick-breaking and pull force overload protection functions, thus fundamentally preventing the rope-breaking accident caused by the overload of the sinking hoisting wire ropes and ensuring the safety of shaft sinking construction.

Technical field
The utility model relates to sinking winch steel rope overload protective device in the mine shaft of vertical well.
Background technology
In the mine shaft mineshaft construction, various preparation of construction in the pit shaft and facility comprise that template, hanging scaffold, grab loader, suspending pump, drain hose, air duct, pressure ventilation pipe, water supply pipe, conveying pipeline, cable, emergency staircase etc. all are to adopt sinking winch to promote and suspention, personnel, material, spoil etc. generally all adopt the single wire winding type mine gig to promote in the pit shaft, nearly 15～20 of lifting in each pit shaft and hanging steel ropes.Sinking winch only is provided with the motor overload protection device.Evidence, existing each safety guard that is provided with all can not be monitored in real time to the pulling force that promotes hanging steel rope, can not prevent to promote equipment damage and the personnel casualty accidents that the disconnected rope of hanging steel rope causes.
Mine concentrates monitoring and controlling system that accident and disaster are predicted, prevented, and guarantees safety of coal mines and effectively production, has played vital function.Concentrated supervision mainly shows: the one, and continuous watch is implemented to concentrate at a distance to the various visual plant operating conditions in down-hole or to subsurface environments such as the comb. gas in operation field and the tunnel, poisonous gas, wind speed, temperature in the safety monitoring device aspect.The sensor distributed points is wide, quantity is big, has realized precognition, prevention to the early stage error state of accident and disaster; The 2nd, control signal to down-hole electric equipment, draft equipment, transportation device, realized lasting telemonitoring etc., and can be sent in the production facilities aspect.
Cheng Shu pulling force and pressure sensor observation and control technology have advantages such as survey precision height, stability be good; but the coal in China industry is in coal automatic gauge system for this The Application of Technology at present, does not appear in the newspapers as yet and be applied to vertical suspention safety guard-safeguard.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point; a kind of sinking winch steel rope overload protective device is provided; on the basis that keeps the automatically controlled defencive function of former sinking winch, increase overcurrent, quick-break and pulling force overload protection function; under different lifting loads, can adjust to overcurrent and fast tripping protection according to the electrical motor outgoing current; can set protection according to the lineoutofservice signal pull value again; fundamentally solve sinking shaft and promote the rope-broken accident that suspension wire rope overload causes, guarantee the shaft sinking construction safety.
The utility model technical solution problem adopts following technical scheme:
The constructional feature of the utility model sinking winch steel rope overload protective device is to have access to pulling force sensor at the terminal string of steel rope connection, or under the bearing seat of hoist(ing) pulley pressure sensor is installed; Control circuit is set, and described control circuit receives the detection signal from pulling force sensor or pressure sensor in real time, and operating value first thresholding that described control circuit is set is made as alarm control, and second thresholding is power-off brake control.
Use of the present utility model is when sinking shaft lineoutofservice signal pull value reaches setting valve, with sound and light alarm, carries out power-off brake then.Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model increase on the basis that keeps the automatically controlled defencive function of former sinking winch is provided with the pulling force overload protection; under different lifting loads, can adjust to overcurrent and fast tripping protection according to the electrical motor outgoing current; can set protection according to the lineoutofservice signal pull value again; fundamentally solve sinking shaft and promote the rope-broken accident that suspension wire rope overload causes, guarantee the shaft sinking construction safety.
Description of drawings
Fig. 1 adopts pulling force sensor mounting structure scheme drawing for the utility model.
Fig. 2 is the utility model adopts pressure sensor mounting structure scheme drawing.
Fig. 2 a is the utility model hoist(ing) pulley and pressure sensor fit structure scheme drawing.
Number in the figure: 1 steel rope, 2 demonstrations and control setup, 3 hanging scaffolds, 4 control cable, 5 central station of floating docks, 6 pit shafts, 7 templates, 8 sinking winch, 9 pulling force sensors, 10 pressure sensors, 11 hoist(ing) pulleies, 12 paralells.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, routinely, various preparation of construction in pit shaft 6 and facility comprise that template 7, hanging scaffold 3 etc. are to be promoted by steel rope 1 and suspended in midair by sinking winch 8, and sinking winch 8 itself is provided with the motor overload protection device.
In the present embodiment, have access to the pulling force sensor 9 that specified pulling force is 100kN to 500kN at the terminal string of sinking shaft hoisting cable 1 connection, it shows and control setup 2 is installed on and is placed in the explosion-resistant enclosure on the hanging scaffold 3.The control setup working power is taken 127 volts of underground signal working powers.Sensor control cable 4 is laid to the downhole sensor control box by ground sinking winch central station of floating dock 5, and alarm contact is serially connected with the automatically controlled alarm loop of winch, sends sound and light signal when pulling force reaches preset value; The trip(ping) circuit contact is serially connected with the automatically controlled safety return circuit of sinking winch, disconnects safety return circuit and realize safety arrestment when pulling force reaches preset value.
This scheme can directly show the actual value of thrust of sinking winch, and except steel rope was conducted oneself with dignity, sensor and fender guard were installed easily, and protection is realization easily, accurately and reliably.
Referring to Fig. 2, another embodiment is that the installation rated pressure is the pressure sensor 10 of 100kN to 500kN under the hoist(ing) pulley bearing seat of sinking winch 8, and it shows and control setup 2 places central station of floating dock 5.
Shown in Fig. 2 a be under the bearing seat of hoist(ing) pulley 11, be positioned on the paralell 12 setting pressure sensor 10.The advantage of this version is that sensor, display control unit and signal transmission line are not influenced by harsh environment, and the stable car driver is the monitoring steel wire rope pulling force at any time.
Two kinds of schemes that Fig. 1 and Fig. 2 illustrate respectively all are that operating value first thresholding with control circuit is made as warning, and second thresholding is made as power-off brake.
The utility model fender guard is active in one's movements, protects reliable, good stability; Adopt seven LED charactrons in the read out instrument, clear display can be accurate to 100N, satisfies the fender guard accuracy requirement; The sensor material adopts the 40CrNiMoA alloy steel, and the maximum tensile strength can reach 1000MPa, can transship 150% safely, satisfies the fender guard requirement of strength.
